一种脱硫汽油的生产方法
摘要：
本发明提供一种脱硫汽油的生产方法。该脱硫汽油的生产方法，包括如下步骤：将汽油原料切割为轻、中、重汽油馏分；对所述轻汽油馏分进行脱硫醇处理，得到脱硫醇轻汽油馏分；对所述中汽油馏分进行吸附脱硫，得到脱硫中汽油馏分；对所述重汽油馏分进行选择性加氢脱硫，得到脱硫重汽油馏分；将所述脱硫醇轻汽油馏分、脱硫中汽油馏分和脱硫重汽油馏分混合，得到脱硫汽油；其中，轻、中汽油馏分的切割温度为35-60℃，中、重汽油馏分的切割温度为70-130℃。本发明的脱硫汽油的生产方法不仅能够实现汽油的深度脱硫，并且辛烷值损失小。
摘要（英）：

The invention provides a method for producing desulfurized gasoline. The method for producing the desulfurized gasoline comprises the following steps: cutting gasoline feedstock into a light gasoline fraction, a medium gasoline fraction and a heavy gasoline fraction; sweetening the light gasoline fraction to obtain the sweetened light gasoline fraction; desulfurizing the medium gasoline fraction by adsorption to obtain the desulfurized medium gasoline fraction; performing selective hydrodesulfurization of the heavy gasoline fraction to obtain the desulfurized heavy gasoline fraction; mixing the sweetened light gasoline fraction, the desulfurized medium gasoline fraction and the desulfurized heavy gasoline fraction to obtain the desulfurized gasoline, wherein the cutting temperature of the light and medium gasoline fractions is 35-60 DEG C, and the cutting temperature of the medium and heavy gasoline fractions is 70-130 DEG C. The method for producing the desulfurized gasoline disclosed by the invention not only can achieve the deep desulfurization of gasoline, but also has small octane loss.
